The specific thing that the ALCU is trying to protect might not be such a good choice, but I appreciate that they are protecting our freedoms.
In fact, I bet the parents/family of the dead soldier feel pretty bad. First, they are very sad that their son is dead. Secondly, they might be questioning why he had to die. But then to have a group at the funeral showing their hate for you and your dead son, thats the icing on the cake.
